KlO_3掺杂聚苯胺电极材料的制备与性能

采用化学法并通过KIO_3和盐酸与苯胺复合掺杂合成掺杂态聚苯胺。用红外光谱和扫描电镜对掺杂态聚苯胺进行了结构形态分析。将掺杂态的聚苯胺混合20％的石墨粉体,制成聚合物复合电极,以锌为负极组成电池,在恒电流条件下进行充放电性能的测试,结果表明,电极开路电位达1.8 V,以20 mA/cm^2恒电流充电,2 mA/cm^2恒电流放电,放电工作平台为1.4 V,设定终止电压为1.1 V时,可持续放电13 h,电池容量较大,结构稳定。

A green and efficient oxidation of benzylic alcohols using H_2O_2 catalyzed by Montmorillonite-K10 supported MnCl_2

Primary and secondary benzylic alcohols were oxidized to the corresponding carbonyl compounds in good to high yields by environmentally friendly and green oxidant, H2O2 catalyzed by Montmorillonite-K10 supported manganese（H） chloride.

“泥婆罗门”疏证

汉文史籍所载吐蕃南疆史事常见"泥婆罗门"一词,前人往往将该词视作"泥婆罗"的误用。综合汉、藏文献和域外研究,"门"应是门隅(Mon-yul)或门巴(Mon-pa)之简称,"泥婆罗"与"门"应为两个部落或属国的名称。
